Re: Need help with my oric 1

Stupid question on your 1st attepmpts: do you 1st plug the power supply to you wall plug, and then plug it to the Oric ? By doing it the other way (plug Oric 1st, then power supply) my Orics remain in this garbage boot screen. I’ve got best results with having PSU connected to both Oric and a mains...

Re: ORIC SDCARD

Is the file browser a separate program that needs to reside on the SD card or should it be loaded just by typing cload””? I transferred a few .tap files onto the root of the SD card and inserted it into the Erebus? If I type cload””, I just get ?memory error. Is there a size limit for the SD card? M...

I got the final missing piece for my Erebus with the arrival of the SD card reader. Gonna put some games on the SD card and try it later this evening.

Re: Atmos ROM

I tried booting with 1.1 ROM burned on the TMS27C128-2JL while Erebus was connected. At least it booted to basic. I couldn’t test accessing the Erebus as I don’t have a keyboard connected to this motherboard.

Re: Atmos ROM

Dusting up this thread. I checked out the two EPROMs that I’ve got. They’re:
TMS27C128-2JL
HN27128-AG-20

I don’t have any mass storage peripherals other than my half finished EREBUS, though. Did that also require /ROMDIS to function?

Re: ORIC SDCARD

I did minor tweaks into the bottom part of the case. I'd forgotten to add fillets into two corners. The updated file is in Dropbox. The link is the same.

Re: IJK-egopad the joypad for Oric by [raxiss]

So, would the Orics be able to communicate with each other, or can you just control two Orics with one joypad?

Perifractic at Retro Recipies is trying to achieve the latter. Although not with Orics, but for example with a C64 and an Atari 8-bit.

Re: ORIC SDCARD

In retrospective, I probably should’ve oriented the PCB the other way around so that the IDC connector was in the back. That would’ve made the front of the case cleaner and enabled to place it side by side with the Oric. The current design facilitates the use of a shorter ribbon cable. I might do a ...

Re: ORIC SDCARD

Here they are. I'm still a beginner with Fusion 360, so there might be errors in the design. If you do print them, please give me feedback how they fit.

If someone with a 3D printer wants to try these out, I can send the .stl files. https://www.dropbox.com/s/8y6joy8wd8agqa3/Photo%2023.7.2020%2C%2022.30.55.png?raw=1 https://www.dropbox.com/s/ldmv8l3fsp2mhkd/Photo%2023.7.2020%2C%2022.30.58.png?raw=1 https://www.dropbox.com/s/347jhrce1cl98gp/Photo%2023...

Re: ORIC SDCARD

Since I didn’t have a case for my Erebus, I thought I’d design my own. Here are a few pics. https://www.dropbox.com/s/69m47y7335yfdgp/Photo%2023.7.2020%2C%2022.30.36.png?raw=1 https://www.dropbox.com/s/62y2fybvn8eddip/Photo%2023.7.2020%2C%2022.30.41.png?raw=1 https://www.dropbox.com/s/hv4nybo2o7o076...

Re: ORIC SDCARD

I got a 28 pin socket and the ceramic capacitors today. I also bought another 27C512, which happened to be UV erasable this time. I tried with the previous EPROM first and unsurprisingly, the Oric wouldn’t even boot. The second EPROM wasn’t empty either, but this time I was able to erase it. Now, it...
